How to make two thor tasks share options?

Question

With Thor one can use method_option to set the options for a particular task. To set the options for all tasks in a class one can use class_option. But what about t

Answer 1

So as not to type "shared_options" all the time, you can also do this:

require 'thor'

class Cli < Thor
  class << self
    private
    def shared_options!
      # list your shared options here
      method_option :opt1, type: :boolean
      method_option :opt2, type: :numeric
      # etc
    end

    # alias original desc so we can call it from inside new desc
    alias_method :orig_desc, :desc

    # redefine desc, calling original desc, and then applying shared_options!
    def desc(*args)
      orig_desc(*args)
      shared_options!
    end
  end

  desc 'task1', 'Task 1'

  def task1
  end

  desc 'task2', 'Task 2'

  def task2
  end

  desc 'task3', 'Task 3'

  def task3
  end
end

Or if you don't want acrobatics with method aliasing, you could just define your own method "my_desc" and call that instead of "desc".
